Acheron HexaLug Muzzle Device – Muzzle Brake 5.56 mm – 1/2x28 UNEF

An effective muzzle brake with an integrated HexaLug interface.

It is compatible with all suppressors equipped with our HexaLug quick-attach system. Thanks to the unidirectional compatibility of the HexaLug system, it is also possible to mount a larger-caliber suppressor. This allows a 7.62 mm suppressor to be installed on a 5.56 mm muzzle brake.

For rifles used primarily or exclusively with a suppressor, we recommend using a muzzle brake instead of a flash hider. The muzzle brake ports redirect high-pressure gases sideways, thereby extending suppressor service life.

Please note that when the rifle is used without a suppressor, the muzzle blast is significantly more intense and affects people standing next to the shooter.

Gen II muzzle device, compatible with Acheron suppressors equipped with a HUB.
